FOURTEENTH ANNUAL YEAR KOOK— PART X 787 



come filled with a straw colored pus. The milking should be done 

 gently and the sore teats washed with a solution of half an ounce 

 of hypo-sulphite of soda in a pint of water. 



BITTER MILK. 



Bitter milk is sometimes produced by nearly all the cows in the 

 herd. In these cases it is usually caused by the feeding of hay 

 containing weeds, or pasturing the cows in a weedy pasture although 

 it may be caused by bacteria coming in contact with the milk after 

 it is drawn. Some cows will produce bitter milk after milking 

 for several months. Such cows should be dried off and if the same 

 trouble appears during the next lactation period, disposed of. 



STRINGY MILK. 



This condition does not occur very frequently unless the cows 

 drink water from stagnant pools, etc. By giving the cows access to 

 pure water only and by giving each affected cow two drams of 

 bisulphide of soda daily. Dr. Law states that the trouble may be 

 permanently arrested. 



BLOODY MILK. 



This condition may result from various causes such as bruises, 

 eating irritant plants, diseased or inflamed udder or eating too rich 

 food. 



TUBERCULOSIS. 



It is needless to say that a tubercular free herd should be main- 

 tained. The herd should be tested annually by a competent vet- 

 erinarian and all reacting animals should be disposed of. It is best 

 to have a quarantine building in which to place suspicious animals 

 for ninety days and then give them a retest as a slight rise in 

 temperature may be due to some other cause.
